I am trying to set up Apache and Webmin so that I can access Webmin by going to https://mysite.com/webmin/. I am using the direction at http://www.webmin.com/apache.html under the "Webmin In A Sub-Directory Via A Proxy" section. I had this setup working before, but I think an update of either Webmin or Apache broke it. Now, I can go the the webpage and I see the login screen. However, when I try to log in, I get an error.I have tried adding the ProxyPassReverseCookieDomain and ProxyPassReverseCookiePath directives to my virtual host config file, but it still doesn't work.

The Apache error log shows nothing when this happens, but the access log shows what could be a 500 error every time.

Any idea what is wrong? Any help would be greatly appreciated.

I got it working. I forgot about another proxy I had set up. Some of those settings were overriding these ones. I just put each proxy in its own <Location> tag and everything works.
